[IPV4]: Fix SNMPv2 "ipFragFails" counter error
When I tested Linux kernel 2.6.17.7 about statistics "ipFragFails",found that this counter couldn't increase correctly. The criteria is RFC2011: RFC2011 ipFragFails OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, e.g., because their Don't Fragment flag was set." ::= { ip 18 } When I send big IP packet to a router with DF bit set to 1 which need to be fragmented, and router just sends an ICMP error message ICMP_FRAG_NEEDED but no increments for this counter(in the function ip_fragment).
